Need help - newbie here!

[cwn8970]

Ok I'll try to explain this to the best of my ability.

I play Vanguard on a laptop - I know - hard to do - but I travel so it's a must. I bought my Dell e1705 (MP061) and had to get the ATI x1400. Found out it wasn't a true 256M card - and shared the RAM on the laptop - so I decided to upgrade.

I bought on eBay a Nvidia 7900 GeForce GO 256M card for my laptop - and upon arrival went thru process of installing it. Upon installation I did notice the FPS increase - but on boot up I noticed TONS of either stuck or dead pixels.

I then called Dell and they replaced my LCD screen. Brand new one. Same issue. I installed the old x1400 - and no dead/stuck pixels. So thus I assumed it was the NVIDIA card.

Spoke with eBayer and he agreed to get me a new one. Sent old one back - got new one and installed it and same dang issue?!?!?!

I read all the forums and cannot determine what the issue is? I upgraded to latest BIOS for laptopn, used latest driver from Nvidia, even made sure it was coold enough - have second set of fans blowing on my desk across laptop to disperse heat.

Any help on why I am seeing a TON more dead or stuck pixels w/ the new Nvidia GeForce GO card? I'm at a loss and would love some assistance.

Hi - one possibility given that you've upgraded from a 64 -256mb card is that the cooling solution doesn't cater for the larger amount of memory (more chips perhaps) and what you're seeing is artifacting and not dead pixels. Overheating VRAM can do some pretty mad stuff.

That's just random ponderings though... I may be totally wrong :)
